Does 30 yuan cancel the deduction of postal SMS and refund the money?

According to my love card, 30 yuan can't return it. The SMS reminder service of Postal Savings Bank is an annual fee service in 30 yuan. If the user agrees to handle this business, 30 yuan will be deducted from the bank card at one time. If users don't need this service, they need to call the customer service hotline of Postal Savings Bank to cancel the service before deducting the money, but the service will be cancelled after the deduction is successful, and the money will not be refunded.
